AI Technical Summary
Technical Problem
Existing medical injection devices have difficulty accurately dispensing medical injection fluids, especially when the graduations are closely spaced, which may cause users to over- or under-deliver fluid.
Method used
The dosage setting assembly, including a stop and removable distal and proximal dosage setting components, uses friction engagement to fix the plunger rod in a predetermined position and control its movement to ensure accurate dosage distribution.
Benefits of technology
It enables precise dosage control of the injection device, avoids excessive or insufficient fluid delivery, and ensures safety during transportation and storage.
